Five games into the 2026 season, the Houston Astros bullpen is already the most pressing storyline in the organization, and it may stay that way for a while.
Josh Hader, the anchor of the back end, is on the injured list with biceps tendinitis. General manager Dana Brown has pointed to a mid-April return, with the possibility it stretches into May. In the meantime, the job of closing games has fallen to Bryan Abreu. Through the first week, that arrangement has raised more questions than answers.
The Abreu Situation
Abreu has been one of the most reliable relievers in baseball over the past three seasons—70-plus appearances each year, 100-plus strikeouts each year, and a 2.40 ERA over that span. His 97 mph fastball and sharp slider made him the logical choice to step into the closer role while Hader heals.
What happened Sunday gave the fanbase pause.
Abreu entered the ninth inning of the series finale against the Angels averaging 93.2 mph on his fastball, a significant drop from his 97.3 mph average last season. He walked two of the three batters he faced before manager Joe Espada pulled him with the Astros holding a two-run lead. Bryan King came in and finished the job.
Espada was measured afterward. “I think it’s just more mechanical than anything,” he said Monday. “We spotted a few things and we’ll be able to get him back on track here for his next outing.” Abreu echoed that assessment.
It’s worth noting Abreu had pitched the night before, throwing 26 pitches Saturday. His velocity in that outing started strong before fading late, a pattern worth monitoring. The Astros have also talked this offseason about protecting his arm by limiting multi-inning usage. Early returns suggest that plan is already being tested.
Whether this is dead arm, a mechanical hitch, or something more serious, the Astros need answers quickly. With Hader unavailable, Abreu is not a luxury—he is a necessity.
Who’s Bridging the Gap?
If Abreu is the closer, the bridge to get there is more complicated. Here’s where things stand through five games:
AJ Blubaugh has been the early standout. The right-hander logged 4⅓ innings in the opening series, struck out five, and did not issue a walk. His ability to work multiple innings has made him one of Espada’s most versatile options.
Kai-Wei Teng has been steady, covering 2⅓ innings while allowing just one hit and striking out two. Like Blubaugh, his multi-inning capability adds value in a taxed bullpen.
Bryan King has appeared in three of the first four games and has been reliable in high-leverage spots, including closing out Sunday’s win. As one of only two left-handers in the bullpen, his workload will be something to watch.
Steven Okert is the other lefty, and one of the more interesting stories on the roster. After years as a journeyman, Okert earned his spot with a strong spring. At 33, this may be his best chance to stick with a contender.
Ryan Weiss and Roddery Muñoz have struggled early. Muñoz, a Rule 5 pick, must remain on the active roster or be offered back to Cincinnati, limiting flexibility. Weiss can be optioned, but was brought in specifically for his ability to cover multiple innings.
Cody Bolton, called up Monday after Christian Roa was optioned to Triple-A Sugar Land, adds another multi-inning arm. The 27-year-old right-hander owns a 5.79 ERA in 34 career appearances, but the Astros are not asking him to be more than a depth option.
The Big Picture
The Astros bullpen has weathered early-season instability before. This group is deeper than it appears at first glance, and the organization’s track record with pitcher development remains strong. But the margin for error is thin.
Hader’s absence removes the safety net. If Abreu’s velocity issue lingers beyond a mechanical adjustment, the back end becomes far less certain. King is already being leaned on heavily. And the multi-inning group—Blubaugh, Teng, Bolton, Weiss—is more about coverage than dominance.
The next two to three weeks will be telling. Hader’s timeline will sharpen. Abreu will either stabilize or force a decision. And Espada will continue sorting through which arms he can trust when it matters most.
For now, the bullpen is functional, watchable, and—if you squint—potentially very good once it’s whole. Getting there is the challenge.
